Answer 2

Incorrect Statements and Explanations:

1. У прудовой лягушки встречается прямой тип онтогенеза. - This statement is incorrect. The direct type of ontogenesis, also known as direct development, is characterized by the absence of a larval stage. In direct development, the embryo develops directly into a miniature version of the adult organism. However, in the case of the pond frog (прудовая лягушка), it undergoes indirect development, which involves a larval stage called tadpole before transforming into an adult frog.

2. Для непрямого типа онтогенеза характерна стадия личинки, которая в дальнейшем претерпевает превращение во взрослый организм. - This statement is incorrect. The indirect type of ontogenesis, also known as indirect development, is characterized by the presence of a larval stage that undergoes metamorphosis to transform into the adult organism. The larval stage is not called "личинка" but rather "личинка" is the Russian word for "larva." This stage is distinct from the adult form and may have different morphology and ecological adaptations. Examples of organisms that undergo indirect development include insects, amphibians (such as frogs and salamanders), and some marine invertebrates like sea urchins.

3. У птиц и пресмыкающихся внутриутробное развитие. - This statement is incorrect. Birds and reptiles do not undergo internal development or viviparity (vнутриутробное развитие). Instead, they exhibit oviparity, which means they lay eggs externally. The eggs are fertilized internally and then laid outside the body, where they develop and hatch. This is true for both birds and reptiles, including snakes, lizards, turtles, and crocodiles.

4. Эмбриональный период онтогенеза - отрезок времени между дроблением зиготы и гибелью организма. - This statement is incorrect. The embryonic period of ontogenesis refers to the stage of development from fertilization to the formation of the major organs and structures of the organism. It does not end with the death of the organism. After the embryonic period, there are further stages of development, such as the fetal period in mammals. The duration of the embryonic period varies among different organisms and species.
